Im a little confused here. It says on the stats for Artis Gilmore 81- 82 (Bulls) that 1 3P was made and that 1 3P was attempted in total. He's 100% when it comes to 3's , but he's only attempted it once during the season. Would he be a good choice in my team? What should i look for if i want somebody in my team who specializes in 3's and throws them often.

jlg beat me to posting the link to Sactown Royalty. I use it as well. In a similar approach to ashamel's original post, I use the Four Factors of Basketball Success to evaluate my teams. There's an article on basketball reference that explains it (don't have time to find the link, but google is your friend). Basically it sets out the four most influential factors and assigns weights to them: EFG(40%) TOV(25%) OREB(20%) FT/FGA(15%). After each season, I evaluate my teams' regular season stats using these weights. While the sim doesn't necessarily weigh things exactly the same way, my championship team did have the best weighted 4 factors score, my best regular season team had the second best score, and my most disappointing team had the worst. So there is a decent correlation between the four factors and sim performance.
